Federal and Navajo officials say that $14.5 million from a bankruptcy settlement with a chemical company will help address contamination at dozens of uranium mine sites on the reservation.

The money is part of a $270 million nationwide settlement announced last month with Tronox, an Oklahoma City-based company that sought bankruptcy protection last year to reorganize its operations and alleviate environmental liabilities and litigation costs.

While the money going to the U.S. Environmental Protection Agency and the Navajo Nation won’t be nearly enough to clean up about 50 sites, it will provide for assessments and radiation screenings to determine the extent of any contamination.
